Answer : [tex]x+3x+x-10=190[/tex] , where x= the money ( in dollars) saved by Abraham.
Money saved by Abraham = $40
Money saved by Steven = $120
Money saved by Christian = $30
Step-by-step explanation:
Let the money saved by Abraham be x ( in dollars).
According to the given statements ,
Money saved by Steven = 3x
Money saved by Christian = x-10
Together they have $190 , so [tex]x+3x+x-10=190[/tex]
[tex]\Rightarrow\ 5x=190+10[/tex]
[tex]\Rightarrow\ 5x=200[/tex]
[tex]\Rightarrow\ x=40[/tex]
i.e. Money saved by Abraham = $40
Money saved by Steven = 3($40)= $120
Money saved by Christian = $40-$10 = $30
